Features of User Defined Fields#
- End users can create these and no special knowledge of the system is required
- Date sensitive changes will carry forward the values
- UserCalcs can read these values, but Workflow UserCalcs cannot access the NewValue of them
- Can be accessed using the P2K_SMGETUDF function by external report writers and by P2K_SMPUTUDF by stored procedures to set the value.
- Interface programs like UEEF and UPPHF can access these natively
Points opposed to User Defined Fields#
- The data is stored in an abstraction table and is not natively linked to the table it is related to.
- This abstraction has the potential, if there are a lot of user defined fields, to impact performance.
Setup and Use of a User Defined Field #
Use the IMUF screen to define the User Defined Field on the table you want the data related to. Note that in a parent-child table relationship where there are date-sensitive children, the parent table is often not permitted to have user defined fields (as seen on IMCD)You may also want to decide on User Defined Columns as your extension structure instead.
